,ing drawn upon an enlarged scale.

-a side elevation of the hook, showing the Be it known that I, HARRY DIFLO, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Hooks for IIames, ot' which the following is a specification.

My invention relates to a safety-hook for haines, and has especial relation to hames for harness for tire departments or hospital, emergency, and police' patrol.

The essential idea of the invention is to provide a safety-hook for attachment with the harness-trace whereby the 'trace may be quickly and conveniently connected with the haine and when so connected be absolutely safe from disengagement with the vhook even under the trying test of a rapid run, with the attendant sudden checking of speed or quick turning of corners, and in which the trace may be conveniently disengaged from the hook when desired. i

The invention consistsin the parts au combination of parts hereinafter described, and pointed out in the claim.

In the drawings, Figure 1 is a front elevation of a pair of haines provided with the safety-hook. Fig. 2 is a sectional view of the hook on line X X, Fig. 3, looking in the direction of the arrow. Fig. 3 is an elevation of the hook, partlyin section, this view be- Fig. 4 is latch when disengaged and raised. Fig. 5 is a plan view of the hook, showing av modified construction.

1 designates the hame, formed with a lower ear 2 and an upper ear 3, bothprojecting at right anglesto the hame and between which the hook 4 is pivotally secured, each ear having a hole 5, through which the bolt 6 passes and upon which the hook is pivotally fastened. Hook 4 is formed with the body portion 7 of a width to pass between ears 2 and 3 and hav-V ing a hole S, through which bolt 6 passes, and from the body portion is extended to form the hook 9, the end of the hook being bifurcated at 10 to receive the tongue 11 of a latch 12, the tongue being pivotaliy secured to the hook by pin' 13, so that the latch 12 may be swung upwardly, as shown in Fig. 4, the articulation of the parts being to allow the latch to be depressed to extend in a line parallel with the upper portion of the hook, as shown in Fig. 3. The upper ear 3 is recessed, as at 14--that is to say, the recess is cut into the body of the ear at a point approximately opposite the normal position of the hook when coupled with the trace and in a position for draft thereon, whereby in order to engage the trace with the hook or to disengage the same the hook must be swung upon its pivot approximately a one-half turn to allow the latch to pass from or into the recess 14.

The operation will be apparent. In order to engage the trace with the hook, the hook is turned forward toward the head of the horse upon which the harness is placed unt-il the latch coincideswith the recess, when the latch may be raised, as shown in Fig. 4, and the trace may be then engaged with the hook, the latch being then depressed, passing through the recess in the ear 3, and as the hook'is turned to -a position parallel with the body of the horse the latch passes beneath the iiange of the ear and is safely locked thereby. This operation is repeated when it is desired to disengage the trace from the hook.

I may vary the means for introducing the latch beneath the ear-as, for illustration, the recess 14 may be dispensed with and the tlange of the ear 3 cut eccentric to the pivotbolt, as at 15, Fig.l 5, the greatest eccentricity being the degree of greatest depth of the recess 14, thereby allowing the latch to drop to a position to .pass beneath the flange, as has been described. This and other modifications are within the scope of my invention without departing from the spirit thereof.

/Vhat I claim is The combination with a hame of a traceconnector comprising ears projecting from the hame, a hook pivotally secured between said ears and provided at its free end with a latch pivoted thereto, said latch constructed as to bring the latch into alinernent with the and arranged to extend between the said ears notch. 1o and be confined thereby when in its closed In testimony whereof I hereby affix my sigposition, a notch in the ear which is adjacent nature in presence of two witnesses.

5 to the latch, said notch being located near HARRY DIFLO.

the front side of the hame and adapted to Vitnesses: permit the rocking of the latch to open the WILLIAM WEBSTER,
